<p>[QUOTE=&quot;gsimonel, post: 3622818, member: 82549&quot;]To elaborate, antoniniani of Probus, like yours - beautiful coin, BTW - were mostly bronze but were coated with a thin silver wash through a process that we don&#039;t yet fully understand. So I&#039;m guessing your coin has never been stripped, because any method of stripping a coin that I know of would also remove the silver wash.</p><p><br /></p><p>Because your coin has retained its silver wash, the surface has toned, meaning that it has reacted with some of the trace chemicals in its environment. If you were to strip off this silver wash (don&#039;t you DARE!) and expose the bronze surface underneath, the coin would slowly develop a patina.[/QUOTE]</p><p><br /></p>
